Concept Introduction:
Valence bond theory: VSEPR theory tells about the shapes of molecules and ions by taking the consideration that the outermost electron pairs are arranged about each atom so that the pairs of electrons are kept at a distance from one molecule to other, thereby minimizing the repulsion of electron-pair.
Lewis structure, otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

- Please count total valence electrons, have lewis structures, resonance structures when applicable, and name the molecular geometry for each central atom.arrow_forwardPredicting deviations from ideal bond angles Consider the nitrogen trifluoride (NF3) molecule. What is the central atom? Enter its chemical symbol. How many lone pairs are around the central atom? What is the ideal angle between the nitrogen-fluorine bonds? Compared to the ideal angle, you would expect the actual angle between the nitrogen-fluorine bonds to be ... 0 口。 (choose one) (choose one) about the same bigger smallerarrow_forwardDepending on the protein under study, the bond angle of a drug molecule can become critical to successfully deactivating a viral protein. For this reason, chemists are frequently concerned with the 3D shape of their molecules and their bond angles. The oxygen atom shown in the structure has a tetrahedral electronic geometry, meaning we would predict that it would have 109.5° bond angles. However, the actual structure, the bond angles are smaller than 109.5°. Explain why this compression occurs. Make sure to discuss what’s happening around/what groups are present around the oxygen atom.arrow_forward

If a pandemonium atom has 8 valence electrons and each vibranium atom has 7 valence electrons, draw the Lewis structure of PbVb4. What is the molecular geometry of the PbVb4 molecule? Pn is the central atom.arrow_forwardAnswer the questions in the table below about the shape of the xenon tetrafluoride (XeF4) molecule. How many electron groups are around the central xenon atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central xenon atom?
